Abstract
Information processing is conveniently achieved by a structure which uses a novel binary switch. The switch can steer two data streams so that they will either cross one another or bypass one another, depending upon external control. A linear array of shift register loops are linked together by these flow-steering binary switches to form a storage structure which is termed a ladder. The ladder provides a variety of data structures. For example, it can alternate between LIFO (last in-first out) and FIFO (first in-first out). It can also dynamically rearrange data items according to recency of usage, in order to improve average access time to any data item. The binary switch and the ladder structure are conveniently provided using magnetic bubble domain technology, although other technologies can also be used.
